That's a long line... but it doesn't break down easily ...

		std::cout << "   Size: "
			  << (size == std::numeric_limits<std::size_t>::max() ? "n" : std::to_string(size))
			  << std::endl;
but maybe that doesn't help much.

Either way, printing the control information is very helpful. And I'm
looking forward to when applciations can use this to interogate the
controls from UI implementations or otherwise at runtime.
